A Periodontal Probe is a dental instrument used to measure the depth of periodontal pockets around a tooth to assess the health of the periodontium. The CP-11.5 and CP-15 probes are specific types of color-coded periodontal probes with markings to facilitate accurate depth measurement. Key Features of the CP-11.5 and CP-15: Color-Coded Markings: These probes have color-coded bands or markings at specific intervals, making it easier to read pocket depths during periodontal examinations. For example: CP-11.5: Usually marked at 3, 6, 8, and 11.5 mm. CP-15: Typically marked at 3, 6, 9, 12, and 15 mm. Material: Often made of stainless steel for durability and precision. Some versions may feature plastic tips for use around implants or sensitive areas. Uses: Measuring periodontal pocket depths. Assessing gingival recession. Evaluating clinical attachment loss. Monitoring periodontal treatment progress. Design: Thin and tapered for easy insertion into the sulcus or periodontal pocket. Rounded tip to minimize tissue trauma. These probes are essential for diagnosing and monitoring periodontal disease and are commonly used by dental professionals. Let me know if you'd like more details about their use or maintenance!
